Ah, I get it now! Thank you very much!

Homework Statement A -10.0nC charge is located at position (x, y) = (2.0cm, 1.0cm) . At what (x, y) position(s) is the electric field - 225,000i N/C? Homework Equations E = (Kq/r^2)*r(hat) The Attempt at a Solution r = sqrt(Kq/E) = .02m = 2cm So coordinates are (0,-2) I...

Thank you, I've managed to figure out everything except the rate at which the atoms collide with one end of the cylinder. I thought it might have something to do with the (Vx)rms, but the numbers don't make any sense to me. Any hints on this part of the question?

Root Mean Square Speed... HELP! A 11.0 cm-diameter, 24.0 cm-long cylinder contains 1.80×1022 atoms of argon at a temperature of 52.0 C. What is (Vx)rms, the rms value of the x-component of velocity? What is the rate at which atoms collide with one end of the cylinder? Determine the pressure in...
